citizen of the United States, residing in Hobolren, county of Hudson,and-Stateof New Jersey, and LINDSLEY SmrnrMons, a citizen of the Unlted-States, residing -1I1 Has- State of New Jersey, have invented new anduseful Improvements in Lighting-Fixtures,-

1? which the following is a (description. Our nvention pertainsto thatclass of lightingfixtures adapted to adjustably hold an incandescentlamp in a fixed position in such manner that its position may readily bealtered as will hereinafter more plainly appear. y

Figure 1 of the drawing is a vertical section of one form of lightingfixture embodying our invention. Fig. 2 is a vertical plan of thefixture shown in Fig. 1. ,Fig. 3 is an elevation of a portionof thefixture shown, in Fig. 1. Fig. l 1s a partial YQITtICZLl section showingin elevation some of the parts shown in section in Fig. 1.

Referring to the drawings, particularly Fig. 1, 1 represents a baseplate which may be attached to .the member indicated at 2 upon which thefixture is supported and held in place as by screws 3. The base plate 1is provided with the extension 4 which is preferably threaded andcarries the sleeve 5 provided with the opening 6 through which the wires7 may be led into the fix ture. The extension 1 is provided on its upperhorizontal face with radial teeth 8 as shown particularly in Fig. 4 andindicated by dotted lines in Fig. 1. The sleeve 9, having the bore 10,is fitted snugly over the sleeve 5 and provided at its lower end withthe flange 11, also having radial teeth engaging the teeth 8 and presseddownwardly thereupon as by means of the spring 12 carried within thesleeve nut '13 threaded upon the member 4: and provided with the flangeportion 1% for engaging the said spring. The sleeve 9 has attachedthereto the revoluble bctticoat 15 carrying the verticalv hollow 3member 16 provided with an arm 17 having the corrugated head '18 uponwhich is fastened the bifurcated member 20v (see Figs. 1, 2 and 3) as byscrews 19. The member 20 is engagement with the 3% by the Specificationof Letters fatent. I Application filed June 14, 1911. Serial, No.633,135.

spring The member 20 also hasthc threaded portion 2 1 uponwhich isthreaded the nlpple 25 carryingthe spring shadeeiigaging means 26 whichmay be pressed into engagement with the shade 28- as by. the

conical bonnet 27 threaded upon-saidv nipple 29. 's the lamp socketcarried by the nipple 25 and adapted to carry the bulb 30. 29 isproperly connected in an obviousmanner .with an'yexternaL circuit as bymeans of wires7. i. r

The operation ofourimprovedfixture is substantially as follows: With thebase plate 1 fixed n'gidly in position as shown in Fig. 1

and the teeth 11 and 8 pressed into engagement by the sp'ringflg asshown,- the member 16" carrying the lamp cannot revolve unlesssuificient force be applied thereto. tocause the sleeve 9 to be raisedagainst the spring 13 and the teeth moved intodifi'erent relativeengagement and thus the lamp is-yieldingly locked in any position intowhich it may be revolved as, for example, when the center line of thearm 17 indicated at a b in Fig. 2 is swung into the position a-c in saidfigure. If it be desired'to change the angular position of the lamp 30this may readily be accomplished by applying sufficient force in thedirection desired to move the lamp to cause the spring bolt 92 to riseover one of the corrugations of the member 18 and fall into the nexthollow and so on until the proper position is reached as, for

example, that indicated by dotted lines in Fig. 1. Thus it will be seenthat the lamp tion into which it may readily be forcedwithout sutferingalteration due to vibration.

We do not wish in any way to limit ourselves to the exact details ofconstruction nor so I,

to the exact mode of operation set forth in this specification anddrawing which are given as one example of lighting fixture embodying theessentials of our invention, for

itis. obvious that wide departure in both may be made without departingfrom the and 'for holding the carrying members in 35 spirit and scope ofour invention which is as set forth in the following claims to wit:
